Neste episódio vamos raciocinar um pouquinho em cima de uma dúvida que talvez tenha passado pela sua cabeça em algum instante mas você nunca deu seguimento depois. Você já se perguntou se quando você tá lá treinando, fazendo uma série de algum exercício, você pára por causa do músculo falhando, do cérebro mandando parar o estresse ou é a sua consciência botando um limite autodeterminado?Vamos descobrir..

Neste episódio discutimos sobre o papel da textura do alimento. Porque raios ela importa, se no fim de tudo, termina em moléculas? Você certamente já pensou ou ouviu falar em algum lugar a frase “meu corpo não vê a comida, vai tudo se misturar lá dentro mesmo, tanto faz então”. E agora, será que é uma viagem desnecessária falar sobre isso? Vamos descobrir..

Neste episódio discutimos sobre o papel do movimento. Ele existe para ir de um ponto A a um ponto B? Ele acontece para trazer informações pro nosso cérebro? Será que tudo junto? Vem descobrir!
